Work-related injuries incur direct and indirect losses to workers, industry, and society, as well as quality-of-life costs to the injured workers families. Direct costs include wages, disability settlements and pensions, assessment and treatment provided by the health care system,diagnostic examinations, hospitalizations, and surgery. Indirect costs include loss of work productivity from the injured workers, employers, and their families, training of replacement workers, lost tax revenues, and administrative expenses. Quality-of-life costs relate to the losses stemming from the chronic pain experienced by the injured workers and other psychosocial burdens on their families. To minimize these losses, the primary goal of rehabilitation have been to improve work capacity and achieve early return to work (RTW).
